.DISCUSSION...
KEY MESSAGE 1...Dry, pleasant weather through the end of the week as
high pressure continues to influence our weather.

Southern New England will see temperatures about 10-12 degrees above
average today and Friday as a surge of warm air advection ahead of a
cold front warms 925 mb temperatures to between +11 and +15C. After
lows in the 30s and 40s this morning,  highs today quickly rebound
into the low to mid 60s, upper 60s for the Merrimack and Connecticut
River Valleys. Highs climb a few degrees higher on Friday with many
places warming near or just above 70 across the southern and eastern
coastal plains (mid 60s for the interior and Cape/Islands). As the
cold front approaches Friday, winds are likely to be gustier than
we`ve seen the last several days...likely 20 to 25 mph at times,
possibly 30 to 35 mph in the higher elevations.

Post-FROPA Friday night, skies clear and winds calm for another
night of radiational cooling. Temperatures will once again drop into
the low to mid 30s for most.

KEY MESSAGE 2...High pressure
likely to maintain dry weather through at least Monday. A slight
risk for some showers Tuesday into Wednesday, but the details
are not yet certain.

The dominant high pressure should finally move off the coast
Sunday night into Monday. Even then, its influence is expected
to slowly diminish into the middle of next week.

There are rather large discrepancies in the evolution of a mid
level ridge across the central USA early next week. The
magnitude and orientation of this ridge will be the determining
factor for the track of a low pressure trying to move east from
the Rockies. at this time, thinking this low pressure will
struggle to move east quickly. That leaves the positioning of
its associated fronts to consider. With the low pressure quite
a ways away from southern New England, there will not be much
push to move them much as well.

Overall, the most likely outcome is that dry weather prevails.
However, a quasi-warm front may get close enough to our region
Tuesday into Wednesday to perhaps trigger a few showers. Not
seeing much moisture to work with, so any precipitation would be
light.
